Just had the ESA shock replaced on my 2010 GS. Bike had just turned 30k miles however I had been complaining to the local dealer from approx 18k and again at the 24k service that, although not leaking or visibly faulty, the shock was not doing what it was supposed to do. My complaints were noted on the computer service record which may have helped my case.
I had paid for the extended warranty however this claim was rejected as I had turned 30k miles, however the local dealer was able to get BMW to stump up for the replacement shock (£1,100) if I paid for the fitting (about 1 hour). Happy with this offer and the new shock is great. I realise now how much the back end of the bike had dropped as I am now back on tip toes at junctions
This is my 4th BMW bike since 2001 and 3 have had replacement shocks under warranty with the earliest failure being at 12k. In my view rear BMW shocks are a weak point in bikes which should handle miles and it is particularly poor that the ESA units are not rebuildable / serviceable given the price.
Traded the 3rd bike (2008 GS) after only 14k but found out from the next owner that he subsequently had to get the final drive replaced under warranty so may have dodged a bullet there and also had the shock replaced.
I average 13 -16k per annum so may be using the bike more than some however none of us would expect BMW cars to need £1,000+ spent on a single replacement shock after only 2 1/2 years / 30k miles - so why is this considered acceptable on their bikes???? It's not like I am lardy, carry pillions or use the bike for extreme enduro; all solo tarmac miles mostly touring (with luggage).
Had fitted Wilbers to my R1200ST on the basis of having a five year warranty and being serviceable and the price for the pair came in not much more than BMW charge for the ESA shock alone. Hyperpro fitted to my R1100S, £190 incl postage to have the rear shock serviced at the factory in Holland.
Come on Mr BMW, fit some better quality shocks and make them serviceable
